When new product’s come out of Sony’s engineer-driven company, you can usually expect to have to keep a few confusing, unbranded designations straight, and Sony’s new televisions — the KDL-60NX810, KDL-55NX810 and KDL-46NX810 — are no exception. Look closer, though, and you’ll see some attractive 3D sets with some impressive functionality.

All of the LCD televisions Sony announced today come with WiFi support, which means the ability to pipe in content from netflix, NPR, Pandora, Slacker, Amazon and other sources. Each supports full 1080p.

Even better, Sony’s continuing its policy of using LED-backlit LCDs with local dimming, which results in the best possible LCD quality levels, meaning that each pixel is lit by LED bulbs which can dim or brighten individually.

As for refresh rates, they are pretty impressive… a necessity for good 3D performance, which, incidentally, these latest televisions support. Just don’t expect glasses or emitter to be bundled in: you’ll need to pony up for the functionality.

Good stuff, but don’t expect these televisions to be cheap: the 60-inch costs $4,700, the 55-inch costs $3,700 and the 46-inch costs $3000. Expect all three televisions to be available for purchase at the end of September.
